Question:	Does this product include infrared or near infrared lights? if so how many and what is the nm depth and nm depth of each color
Answer:	No
Question:	How does device stay propped up, if used on face/neck
Answer:	Needs batteries
Question:	Must u wear protective eye wear with it
Answer:	Your aube th111gfci-p 120 vac thermostat can control a resistive load of up to 2000W @ 120 V - the Honeywell TH115-AF-GA appears to be designed for a load of 1800W @ 120 V, that is, slightly less. If your electric floor heating system draw less than 1800W you should be good to go. However, you may want to figure out why the previous thermostat died... if it died because of overload the Honeywell TH115-AF-GA will not work.
Question:	What are the wave lengths on the other colors? I only see the red is 640nm
Answer:	The sensors that I have used with this thermostat are the Honeywell models. I always run a backup sensor also, just in case. For $10 it's worth it. The sensor is available for less in places other than amazon - just google the part #. IMO - The sensor should match the thermostat, not the floor mat. But you would have to check w/ Honeywell to see if one from suntouch is compatible. Personally, I wouldn't take the chance since at best maybe you got one included with your mat and you'll spending $20 for 2 Honeywell models. Is it really worth any risk at all to save $10? Bottom line, you would have to check w/ Honeywell to see if it is compatible. But why take the chance? I'd be surprised if Honeywell would tell you that any sensor other than theirs is approved and tested for use but ... you can try. Did you ask Suntouch? If they only make mats and not thermostats then maybe they've done testing with different combinations. That's a good place to check. Still it's not much money and IMO - you need 2 sensors in case you have a failure - either over time or during install. Sensor wires are THIN and fragile - unlike the heating wires themselves. It wouldn't take much to nick one.
